I think it's a cool project. It looks slick and no doubt was a lot of work.
Would I ever use it though? Of course not.
It in fact goes in the exact opposite direction of computing for me. I am increasingly moving away from any product that relies on WiFi/connectivity.
So nice to have your own media (movies, music) and not have to worry about an always-on internet to be your streaming bottleneck (never mind the inefficiencies of requiring a personal, on-demand, high-bandwidth movie stream). But then to take and put all your tools and desktop in the cloud as well?
I guess it's why I have no use for Chromebooks either.
